__createIterableObject(), used in the numerous "generic iterables" tests, is defined as:

function __createIterableObject(arr, methods) {
        methods = methods || {};
        if (typeof Symbol !== 'function' || !Symbol.iterator) {
          return {};
        }
        arr.length++;
        var iterator = {
          next: function() {
            return { value: arr.shift(), done: arr.length <= 0 };
          },
          'return': methods['return'],
          'throw': methods['throw']
        };
        var iterable = {};
        iterable[Symbol.iterator] = function(){ return iterator; }
        return iterable;
      }

^[2] Flagged features have to be enabled via --harmony flag

^[3] Flagged features have to be enabled via --harmony or --es_staging flag

^[4] Executed in Node.js/JVM mode via graalvm/bin/node --jvm.

^[5] Executed using js --js.intl-402.

^[6] The feature can be enabled with use strict and JavaScript flag "--harmony-tailcalls" in certain versions of Node.js. Since Node.js 8.2.1, the V8 flags --harmony-tailcalls and --harmony-explicit-tailcalls have been removed. See: Chrome Platform Status, blog in JavaScript in Plain English, and V8 Dev Blog for details.

^[7] Requires the properTailCalls compile option.

^[8] TypeScript's compiler will accept code using this feature if the --target ES6 flag is set, but passes it through unmodified and does not supply a runtime polyfill.

^[9] Requires the downlevelIteration compile option.

^[10] This feature is supported when using Babel with core-js.

^[11] This compiler requires generic iterables have either a Symbol.iterator or non-standard "@@iterator" method.

^[12] Does not work with the downlevelIteration compile option.

^[13] Firefox incorrectly produces an error in strict mode if the method is named "arguments", "eval", or "delete".

^[14] The feature has to be enabled via "Experimental Javascript features" setting under about:flags

^[15] This feature is supported when using TypeScript with core-js.

^[16] Safari 12 caches TemplateStrings using a GC-able "CodeBlock". But TemplateStrings are supposed to always be identical! When the CodeBlock is reclaimed, the TemplateStrings' identity is broken. Thankfully, [[Call]] vs [[Construct]] generate different CodeBlocks, which exposes the broken behavior.

^[17] Hermes isn't currently supporting destructuring in catch parameters

^[18] This feature features requires an optional transformer setting.

^[19] Note that prior to ES6, it was recommended that ES5 implementations forbid block-level declarations in strict mode.

^[20] Hermes isn't currently supporting classes apparently

^[21] Requires native support for Object.prototype.__proto__

^[22] This compiler transforms extends into code that uses native Object.prototype.__proto__ or copies properties from the superclass, instead of using the prototype chain.

^[23] TypeScript transforms extends into code that copies static properties from the superclass (but uses the prototype chain for instance properties).

^[24] This feature requires native generators or regenerator-runtime, it's a part of babel-polyfill or babel-runtime.
